Thin and uniform layer on textured substrates provides enhanced efficiency in polymer solar cellsIowa State University and Ames Laboratory researchers have improved the efficiency of polymer solar cells through the use of a new process that increases light absorption.

Lead researchers working on the study include Sumit Chaudhary, Iowa State assistant professor of electrical and computer engineering; Kanwar Singh Nalwa, a graduate student in electrical and computer engineering and student associate of the Ames Laboratory; Kai-Ming Ho, an Iowa State Professor of Physics and Astronomy and an Ames Laboratory faculty scientist, and Joong-Mok Park, an assistant scientist in the Ames Laboratory. Together, these researchers have created a new process that increases the efficiency of solar cells.
